Technical Field

[0001] The utility model relates to the technical field of spectrometers, in particular to a split excitation head device. Background Art

[0002] In a spectrometer, the excitation head is an important component. The product to be tested is placed on the excitation head for excitation, and the generated spectrum is sent into the optical chamber through a lens and a reflector. For some mobile spectrometers, the excitation head is installed on a handheld gun. The existing installation structure is shown in the patent with patent number 202223547694X. The excitation head shell mounted on the excitation head is fixed by screws. Installation and disassembly require the use of tools such as screwdrivers, which is inconvenient to operate. Summary of the Invention

[0003] In order to solve the above technical problems, the utility model provides a split excitation head device, which can facilitate the installation and disassembly of the excitation head housing.

[0004] The technical solution is as follows: a split excitation head device, which includes an upper reflective chamber base, a lower excitation head shell, and an excitation head, characterized in that the upper reflective chamber base is installed on a rear fixing plate, and a sleeve is provided on the rear fixing plate for allowing the excitation head to pass through. A lens mounting block is provided at the bottom of the upper reflective chamber base, and a lens is installed in the lens mounting block. The lower excitation head shell is sleeved on the excitation head and the top abuts the lens mounting block. The rear end of the lower excitation head shell abuts the sleeve and the abutting point is connected by a nut.

[0005] It is further characterized in that a convex ring is provided at the front end of the sleeve, the nut is slidably fitted on the sleeve, a retaining ring with an inner diameter smaller than the outer diameter of the convex ring is provided at one end of the nut, a connector is provided at the rear end of the lower excitation head housing, the connector abuts against the convex ring, and the connector is provided with an external thread that cooperates with the nut;

[0006] The outer peripheral surface of the nut is a rough surface.

[0007] After adopting the utility model, the lower excitation head shell is fixed by means of threaded connection. No tools are required and the installation, locking and disassembly operations can be performed by directly manually screwing. The use is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] See Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a split excitation head device includes an upper reflective chamber base 1, a lower excitation head shell 2, and an excitation head 3. The upper reflective chamber base 1 is installed on a rear fixing plate 4, and a sleeve 5 is provided on the rear fixing plate 4 for allowing the excitation head 3 to pass through. A lens mounting block 6 is provided at the bottom of the upper reflective chamber base 1, and a lens is installed in the lens mounting block 6. The lower excitation head shell 2 is mounted on the excitation head 3 and the top is against the lens mounting block 6. The rear end of the lower excitation head shell 2 is against the sleeve 5 and the abutting point is connected by a nut 7.

[0013] A convex ring is provided at the front end of the sleeve 5, and the nut 7 is slidably mounted on the sleeve 5. A retaining ring with an inner diameter smaller than the outer diameter of the convex ring is provided at one end of the nut 7. A connecting head 8 is provided at the rear end of the lower excitation head shell 2. The connecting head 8 is against the convex ring, and an external thread that cooperates with the nut 7 is provided on the connecting head 8. The outer peripheral surface of the nut 7 is a rough surface, which can facilitate the screwing operation.

[0014] During assembly, the lower excitation head shell 2 is put on the excitation head 3, with the rear end against the convex ring of the sleeve 5 and the top against the lens mounting block 6, and then the nut 7 is moved to the connection position, and the nut 7 is screwed on the external thread to complete the fixed connection of the lower excitation head shell 2; when disassembly is required, directly screw the nut 7 to separate it from the connecting head 8, and then the lower excitation head shell 2 can be disassembled, which is simple and convenient.
